Ok, I am not looking for detailed code, just trying to put together a viable strategy, and need to understand if I pinpointed the right technology for someone else to actually deal with.
Here is what I'm doing: Let's say I have a e-greeting card company and I want offer the sender the opportunity to 'add some money' (via paypal) to their $1 greeting card, as an additional gift to the user... the same way you might stuff a 20$ bill in a physical card. But here is my issue: I don't want to charge the sender $1 for the card + $20 for the gift = $21... I want to charge the user $1 for the card, and facilitate a second transaction to their friend via paypal, so I'm not liable for the whole transaction if there was fraud. Make sense?
Does anyone have any experience with this? They have 5 million options over there... is this the right solution?
